* feat: add scheduler functionality with cron-style task management
- Implemented a new scheduler subagent to automate recurring tasks using cron expressions.
- Enhanced the subagent factory to include the skill manager and auxiliary chat model for the scheduler.
- Created a YAML configuration for the scheduler with a detailed system prompt and toolset.
- Updated README files to include documentation on scheduled tasks and usage examples.
- Added tests for the scheduler, including command execution, scheduling tools, and middleware integration.
- Introduced new dependencies for timezone handling and ensured compatibility in the project configuration.
* fix(async-notifier): ensure fallback hint is used for unknown notification kinds
* feat: enhance scheduling functionality and improve system message handling
* fix: session lost after evoscientist restart
* feat: Implement memory worker thread deletion on completion
- Added synchronous and asynchronous functions to delete memory worker threads after they finish execution, ensuring no residual checkpoints are left in the database.
- Enhanced `_watch_memory_worker_run_sync` and `_watch_memory_worker_run_async` to invoke deletion functions upon confirming worker completion.
- Introduced tests to verify that worker threads are deleted correctly upon successful completion and that failures in deletion do not affect the overall worker status.
- Updated session management to ensure that only relevant threads are restored from the database, preventing exposure of internal or unrelated workspace threads.
- Implemented a purge function to clean up leftover worker checkpoints during server startup.
* feat: Implement short thread ID display for CLI and session hints
* fix: ensure proper accounting and deletion order for memory worker threads

* feat(memory): add observation memory lifecycle
Add file-backed observation memory with deterministic markdown records,
structured record_observation tooling, startup indexing, and
profile/observation prompt guidance.
Launch post-turn and post-subagent EvoMemory workers through LangGraph
dev so completed runs can update profile memory, save durable
observations, and write subagent execution summaries without blocking
the active agent.
Wire memory middleware into the main agent, subagents, async graphs, TUI
status reporting, worker activity accounting, and observation-aware
research prompts, with regression coverage for storage, lifecycle
scheduling, graph registration, status display, and stream reset
behavior.
* fix(cli): sync background agent server on resume
Resume flows now need to keep the LangGraph dev background server
aligned with the active workspace even when async subagents are
disabled. EvoMemory workers use that server too, so gating resume-time
sync on enable_async_subagents could leave workers pinned to the launch
workspace after resuming a thread from another workspace.
Run workspace sync unconditionally for Rich CLI and Textual resume
paths, while preserving WorkspaceMismatchError handling so failed sync
aborts the resume before mutating the active thread or workspace.
Propagate aborted resume callbacks through the command UI so
channel-issued /resume commands do not send false success or history
output. Channel slash dispatch now treats CommandManager-caught command
errors as command errors and skips completion hooks for those failed
commands.
Add regression coverage for disabled async subagents, callback aborts,
and channel command error reporting.
* fix(cli): prepare serve resume workspace before adopting
Load the resumed workspace agent and sync the background server as a
single pre-adoption step. Restore the previous active workspace if
preparation fails so serve mode keeps using the old session
consistently.
* fix(memory): untrack abandoned worker status watches
Stop treating watcher shutdown as confirmed worker completion. Terminal
worker statuses still count memory deltas, while poll failures or
watcher setup failures now remove the active run without crediting
partial outputs.
* fix(cli): report channel command failures accurately
Treat command_error as a None sentinel so empty error strings still
fail, and let TUI resumes continue only on non-mismatch
background-server sync failures while reporting degraded mode.
* fix(stream): clear memory counters for resume streams
Reset completed-memory counters for every new agent stream, including
Command-based HITL and resume streams, so saved-memory indicators do not
leak across turns.
* docs(tools): make observation recording guidance conditional
Clarify that agents should call record_observation only when the
observation tool is available, preserving the existing durability and
usefulness criteria.
* feat(config): add controls for profile and observation memory
Add config flags for profile memory, observation memory, observation
writer placement, and background memory workers.
Wire the controls through main agents, subagents, EvoMemory middleware,
and memory lifecycle workers so observation writes can be assigned to
the live agent, subagent worker, both, or neither. Keep turn memory
workers profile-only and make prompts reflect the available observation
read/write paths. Skip langgraph dev startup when neither async
subagents nor memory workers need the background server.
Add coverage for config parsing, prompt gating, middleware wiring, and
worker tool availability.
* test(cli): include memory defaults in serve config stubs
* fix(memory): offload async worker launch blocking calls
Run the langgraph-dev health check and memory-output snapshot in worker
threads from the async EvoMemory launcher so it does not block the event
loop.
* chore(memory): harden turn worker subagent guardrail
* chore(memory): refresh profile context per request
* fix(memory): offload async profile file reads
* fix(memory): offload async worker completion accounting
* Refactor sub-agent architecture and introduce async support
- Removed the legacy subagent.yaml file and replaced it with individual YAML files for each sub-agent in the subagents directory.
- Updated the load_subagents function to support both directory and single file layouts for loading sub-agent configurations.
- Added new langgraph_dev module for managing async sub-agent lifecycle and deployment.
- Created graphs for async sub-agents (writing-agent, data-analysis-agent) and updated langgraph.json for deployment.
- Introduced new sub-agent definitions for planner, research, debug, code, and writing agents with appropriate system prompts and configurations.
- Enhanced package data inclusion in pyproject.toml to accommodate new sub-agent YAML files.
* Refactor code for improved readability by consolidating conditional statements and formatting
* feat: enhance async sub-agent support with workspace synchronization and user feedback
- Added console status messages during async sub-agent server startup and workspace synchronization to improve user experience.
- Implemented a new WorkspaceSyncWidget for live feedback during workspace sync operations.
- Updated onboarding to reject occupied ports and ensure proper workspace handling for async sub-agents.
- Introduced locking mechanisms to manage concurrent access to langgraph dev processes and workspace states.
* feat: add async sub-agent configuration and server management functions
* feat: improve port occupation handling and log file management in start_langgraph_dev
* feat: enhance async sub-agent handling and introduce comprehensive tests
- Updated `_maybe_swap_async_subagents` to improve async sub-agent management, ensuring internal flags are stripped before handoff.
- Enhanced port management in `onboard.py` to allow reuse of occupied ports if already running by the same service.
- Introduced file locking in `manager.py` to prevent race conditions during concurrent CLI invocations.
- Added new tests for async sub-agent swapping and langgraph manager functionalities to ensure reliability and correctness.
- Updated dependencies in `pyproject.toml` to include `psutil` and `filelock`.
* fix(docs): clarify sub-agent configuration in README
* test(manager): isolate _PID_DIR + tighten reuse-path assertion
Addresses CodeRabbit review on tests/test_langgraph_manager.py:
- Patch _PID_DIR to tmp_path so the FileLock setup in
ensure_langgraph_dev doesn't mkdir the user's real
~/.config/evoscientist/ dir as a test side-effect.
- Tighten "result is None or hasattr(result, 'poll')" to a strict
"result is None" — the reuse path returns None unconditionally,
so the OR clause was hiding potential regressions.
